Foreword As with most blockchains , Ethereum nodes aggregate transactions and form them into blocks, and once miners solve the consensus mechanism (currently Ethereum’s ETHASH PoW), those transactions are considered valid, as will the miners who solved the block Choose which transactions from this pool will be included in the block, this is usually determined by gasPrice transactions, there is a potential attack vector here, an attacker can observe the transaction pool for transactions that may contain a solution to the problem, smart contract audit services modify or revoke the attacker’s permissions or change the state in the contrac`t that is unfavorable to the attacker, the attacker can then get the data from this transaction and create a higher level transaction gas Price and include its transaction in a in the block.
